The delayed rise of present-day mammals

... that the ancestors of modern mammals were able to quickly evolve and spread to fill many of the empty niches left behind following the mass extinctions of dinosaurs and many other large animals when a huge asteroid crashed into the Earth about 65 million years ago. An international research team reached ...

New science of metagenomics 'will transform modern microbiology'

...he data generated by the Human Genome Project were quickly made available in a public database, making them more valuable to researchers, the committee urged that metagenomic data likewise be made publicly available in international archives as rapidly as possible. The databases should include not only gene...

Why some people are more attractive than others

...responsible for attractive features should spread quickly through a population, resulting in males becoming equally attractive, to the point where sexual selection could no longer take place. However, new research by Professor Marion Petrie and Dr Gilbert Roberts at Newcastle University, England, suggests ...

Ultrathin films deliver DNA as possible gene therapy tool

...king the polymer structure slightly can change how quickly the films erode and thus how long cells are exposed to the gene therapy. "We ultimately need an effect prolonged enough to be therapeutically relevant - whatever time scale that might turn out to be, " explains Lynn. The films start to break down wh...

New metal crystals, formed on a cotton assembly line

...ickel and other metal and metal-oxide nanocrystals quickly and of uniform size, Shin said. The metals display catalytic, electrical and optical that would not be present in larger or odd-sized crystals. The acid converts the cellulose to a large, stable crystallized molecule rich in oxygen-hydrogen, or hyd...

'Dipstick' test could reduce risk of food poisoning by rapidly detecting spoilage

...eloping a consumer test kit that people can use to quickly and accurately determine if food products are spoiled or safe to eat. Described today at the 233rd national meeting of the American Chemical Society, the new diagnostic test, which researchers describe as a disposable dipstick, is capable of rapidl...

DNA layer reduces risk of reserve parts being rejected

...Layer by layer However, enzymes in the body will quickly break down a DNA coating. A method therefore had to be found to firmly attach the DNA to the implant surface. Van den Beucken used the Layer-by-Layer deposition technique (see Figure 1) to produce a multilayer coating. This coating was tested in cell...

Study shows metabolic strategy of stressed cell

...ollowing the shutdown of CoA production, the cells quickly recycled CoA from other jobs so it could concentrate all its efforts on a single task: extracting life-supporting energy from nutrients in the mitochondria. Mitochondria are the powerhouses of the cell, so-called because these bags of enzymes host a ...

No pain, DOE Joint Genome Institute gains coveted ergonomics prize with 'Shake 'N Plate'

...the DOE JGI Instrumentation Group. The design was quickly fabricated in the LBNL shops and put into production use. The device removes almost all of the weight from the operator's arms and actually improves the process throughput. The "Shake 'N Plate" upstaged such big names in the competition as Boeing...

The Parkinson's Institute to conduct Phase III Clinical Trial of creatine for Parkinson's disease

...ipating in this study, which may help us move more quickly toward developing a therapy that could change the course of this devastating disease," says Elias A. Zerhouni, M.D., director of the NIH. "The goal is to improve the quality of life for people with Parkinson's for a longer period of time than is pos...

Blood's clotting cells harbor 'ticking time bombs,' finding may help extend blood supply

...nized as foreign by a recipients immune system and quickly cleared from the bloodstream. The problem at room temperature is that biological processes occur quickly, leading to a rapid decline in viability, Kile said. That decline, in addition to problems with bacterial contamination, has precluded platelet...

Notorious cancer gene may work by destroying messenger

...y player in an unusual mechanism that cells use to quickly stop production of certain important proteins. Researchers discovered that PMR1 is activated or turned on by another molecule, an energy-packing protein called Src (pronounced sark). Discovered in 1977, Src became the first oncogene mutated ...

Gene hunters, patent prospectors leave indigenous communities in Pacific feeling besieged, betrayed

... blood samples from indigenous people. The project quickly ran into opposition from indigenous groups. "We know our creation stories and we know who our ancestors are," writes Le'a Malia Kanehe, a Native Hawaiian lawyer from Honolulu, USA, and Legal Analyst for the Indigenous Peoples Council on Biocoloniali...

Failure to meet United Nations sanitation target could affect millions of the world's poorest

...rban areas, because you can serve more people more quickly when they are clustered together," she said. "From a public health perspective, you may also argue that it's the smart thing to do, because densely settled areas are particularly vulnerable to the transmission of waterborne diseases. But from an ethi...

Stress and nerve cells survival in rats; finding may open window for depression treatment

...h two older rats for 20 minutes, the resident rats quickly pinned down and, in many cases, bit the intruder. The team reported that intruder rats were fearful and acted depressed around the bigger, more mature animals and had stress hormone levels six times as high as young rats that didn't experience a stre...

Iowa State University botanists identify new species of North American bamboo

...e we actually saw the plants in the field, we knew quickly that there were two distinct species," Clark said. "But we kept hearing about a third plant, called hill cane." And as soon as they saw it, they knew it was different....

Stealth camouflage at night

Genes and groups of genes commonly shared between species, studies show

...can gain a new function that helps them adapt more quickly to the same type of environment - in this case, a hot, highly acidic, metal-rich broth. This is the first observation of exchange of very large genomic blocks between organisms in a natural microbial community, according to UC Berkeley's Jill Banfi...

Location, location -- Cell sizes, lives influenced by host size

...are linked to the whole organism. But the sizes of quickly dividing cells are independent of the organism." Neurons are essential parts of brain networks that retain memory, the researchers said, while fat cells are storehouses of energy that are vital for an animals survival when food supplies are short. ...

Regardless of global warming, rising CO2 levels threaten marine life

..."Coral reefs will go the way of the dodo unless we quickly cut carbon-dioxide emissions." Over the next few decades, we may make the oceans more acidic than they have been for tens of millions of years, Caldeira said. And thats bad news....
